High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
With only a moderate freeze overnight, the onset of loose wet avalanches is possible. Keep a close eye on the snowpack strength, you may encounter isothermic (unsupportive) conditions, generally from mid elevations. Be selective in the terrain you ski/ride. if the snow feels rotten, leave the slope and choose another aspect, watch for slopes that lead to terrain traps.

Alpine level
High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
Expect windslab development at ridge-line on S aspects. This new snow is sitting on an icy base, bonding strength is improving. Avoid entries to steep terrain at ridge-crest, watch for 'pillows' of stiff slab snow, be cautious around uterrain traps and steep gullies.

Recent Avalanche Activity

Recent Avalanche Activity
No new activity over the past 24 hrs with good stability. Today solar aspects may see an increase in wet slide activity with only a light surface freeze overnight. Any windslab development generally found above 2000 m.

Current Snowpack Conditions

Current Snowpack Conditions
Good bonding of yesterday's new snow to the old surface. Expect any moist snow to develop a crust from cold overnight tempss. From mid elevations wet slide activity is possible on solar aspects with a mainly fine day ahead. If heading backcountry be aware of snowpack strength, if you find the pack turning isothermic (unsupportive) move onto shadier aspects.

Mountain Weather

Mountain Weather
A mainly fine day ahead with occasional cloudy periods. Freezing level steady at around 1800 m. Winds from the NE increasing as the day progresses.

Sliding Danger

Slide For Life
With colder night temps expect icy conditions if heading out early, good idea to carry an ice axe and crampons at this time of year. No good having them at home when you need them !
